Filter by:The iliac crest is one of the most commonly used bone graft sources, especially in pediatric pelvic osteotomy operations for developmental dysplasia of the hip (DDH) and Legg-Calve-Perthes disease. In this study, we aimed to identify the effects of inner side and two-sided approaches for iliac crest bone harvesting on post-surgery ilium growth in children.
This observational study aims to determine the efficacy and safety of the Shark Screw® transplant for osteotomy and arthrodesis in hand and foot surgery.
Medial open wedge high tibial osteotomy is a surgery performed to treat knee osteoarthritis in young patients.Recently with our department advance of technology, the investigators performed computed tomography for the patient's lower limb and 3D reconstruct the image. Based on the 3D image, the investigators planned our planned osteotomy cut on computer software Materialize 3 and the investigators then 3D printed a metal jig that has a slot to produce the osteotomy and also protected the neurovascular bundles. Therefore these metal jigs are specific to each patients. The investigators have performed a few cases of HTO under this extra metal jig protection and guidance and noted it has improved accuracy and safety clinically. However, whether it has scientific significance difference in accuracy is not known.
A common surgical treatment for posterior tibial tendon dysfunction (and the resulting flat foot) is the correction through a calcaneal lengthening osteotomy of the lateral column (LLC). Clinical studies showed pain relief and functional improvements through different scores. However, according to clinical experience, some patients complain about a limited ankle dorsiflexion after LLC surgery. Several joints of the foot (talocrural, subtalar, talonavicular, calcaneocuboid) contribute to the overall range of motion in foot plantarflexion/dorsiflexion and pronation/supination. Changes in the range of motion in one joint can affect all the other joints. For instance, it was shown that a fusion of the talonavicular joint removes most of the residual hindfoot motion in plantarflexion/dorsiflexion and pronation/supination. Because the lengthening of the lateral column presumably decreases the mobility of the medial column and thus of the talonavicular joint, this surgery can influence the range of motion of the other joints, and hence contribute to the reported decreased ankle dorsiflexion motion. Patients after LLC have less plantarflexion of the first metatarsal throughout stance of level walking and less inversion of the hindfoot during push-off compared to healthy subjects. Uphill walking requires more ankle plantarflexion and dorsiflexion than level walking. A limitation of the ankle joint mobility especially in dorsiflexion could therefore lead to additional or greater changes in gait patterns (hindfoot and forefoot kinematics) during uphill walking. The primary objective is: • To compare differences in hindfoot and forefoot kinematics between level and uphill treadmill walking in relation to passive range of motion The secondary objectives are: - To compare lower leg muscle activation during level and uphill treadmill walking between patients after LLC and healthy subjects - To test the association between muscle strength, muscle activation patterns and hindfoot and forefoot kinematics during level and uphill walking and heel rise - To relate clinical outcome of LLC surgery by functional scores to passive range of motion
The aim of this study is to determine the possible reducing effects of different concentrations of lavender oil on preoperative anxiety in orthognathic surgery patients who have high anxiety during preoperative wait.
